The upper and lower central guide bodies 20 and 30 move forward while moving toward the center side in the frontage direction along the linear groove portion 63. Then, as shown in FIGS. 7A to 7C, when the side guide body 50 reaches the curved groove portion 62 of the curved guide groove 61, the upper end side shaft 18 and the lower end side shaft 19 rotate about the fulcrum. The side guide body 50 moves along the curved groove portion 62 so as to draw an arc so that the storage body 10 rotates. Then, as shown in FIGS. 7C and 7D, when the rotary housing 10 is rotated, it is in the final state, that is, when the side guide body 50 reaches the other linear groove portion 63, the side guide body. The upper and lower central guide bodies 20, 30 move rearward while 50 moves outward along the other linear groove portion 63 in the frontage direction. As a result, the rotary housing 10 is rotated about the upper and lower shafts 18 and 180 by 180°, and the front and rear thereof are inverted. In this way, the rotary storage device 1 rotates the rotary storage body 10 around the shafts 18 and 19 while moving the upper and lower shafts 18 and 19 of the rotary storage body 10 in the front-rear direction, and The front and back can be switched (switched).
